This year, four of our colleagues ran the OCC as part of the Ultra-Trail du Mont-Blanc series. The race is 56km (35 miles) long and takes in 3,500m (11,500 feet) of ascent.

Crossing the finish line in Chamonix were Maud, a product development manager; Stéphane and Sophie, both sales reps, and designer Flavien. Flavien is used to these kind of events as he's run in the UTMB before (the OCC in 2015 and the CCC in 2017), but for the others it was a first.

We found them limping and slumped on sofas shortly after the race. They told us all about it over coffee.

On 1st September, the world trail-running elite met for the 15th edition of the Mont-Blanc Ultra-Trail® in Chamonix. Today, in his web series, Xavier Thévenard talks about this incredible race in which he finished in fourth place, just short of the podium of legends: UTMB® - 20-hour goal.
